> TPCDS queries q15, q19 are failing when hive.vectorized.execution.mapjoin.native.fast.hashtable.enabled  is set to true. 
> Setup should include atleast 2 node cluster.  It's passing when the cluster has only 1 node. 
> The wrong result is also random(on each run I get different random wrong values).
> Small repro query on TPCDS dataset
> {code:java}
> select ca_zip, count(*)
> from catalog_sales_small, customer_small, customer_address_small
> where cs_bill_customer_sk = c_customer_sk
> and c_current_addr_sk = ca_address_sk
> group by ca_zip
> order by ca_zip
> limit 100;
> {code}
> If we set the following properties, we get correct results
> {code:java}
> set hive.vectorized.execution.enabled=false; - Correct results
> {code}
> OR
> {code:java}
> set hive.auto.convert.join=false; - Correct results
> {code}
